= Add Empty Gemetry TIN File to GeoPackage Database =
<ol>
<li>Click on the ‘Import Empty File’ symbol from the TUFLOW Plugin toolbar. <br>
<br>
[[File:ImportEmpty_a.PNG]]<br>
<br>
<li>This opens the Dialog shown below. The TUFLOW plugin accesses the 'Empty Directory' created when the project was configured and provides a list of files to choose from. It appends the 'Empty Type' to the beginning of the 'RUN ID' and the 'Geometry Type' letter to the end. This becomes the name of the file. Make the following selections:
:*Select '2d_ztin' from the Empty Type list.
:*In the Run ID box write: 'Development_001'.
:*Tick the 'Regions', 'Lines' and 'Points' Geometry Type.
:*In the Spatial Database Options, select 'All to one'. Navigate to the '''TUFLOW_SWMM_Module_02/TUFLOW/model/gis''' folder and save the GeoPackage database as '''TS02_001.gpkg'''.
:*Click 'OK'.
<li>A layer called '''2d_code_M01_001_R''' in a region format with the relevant TUFLOW attributes is created. The TUFLOW plugin automatically creates a GeoPackage database called '''M01_001.gpkg''' in the '''Module_01\TUFLOW\model\gis''' folder, saves the '''2d_code_M01_001_R''' layer within it and opens it in the QGIS Layers panel.<br>

<br>
</ol>
The model extent is provided in a common GPKG layer:
<ol>
<li>Load in the '''Model_Boundary''' from the '''Module_01\Tutorial_Data''' folder. Drag and drop the '''Model_Boundary.gpkg''' into QGIS.
<li>The region object in the '''Model_Boundary''' is not in the TUFLOW file format and needs to be copied into the '''2d_code_M01_001_R''' layer to have the correct attributes.
<li>Make the '''2d_code_M01_001_R''' layer editable by right clicking the layer and selecting 'Toggle Editing'.
<li>Select the '''Model_Boundary''' file by left clicking on it once in the Layers panel and use the 'Select Features' tool to highlight it. <br>
<li>Select 'Edit' from the top QGIS tab and 'Copy Features' from the drop down menu.
<li>Select the '''2d_code_M01_001_R''' layer in the Layers panel by left clicking on it once. Select 'Edit' from the top QGIS tab and click 'Paste Features' from the drop down menu.<br>
<br>

<br>
</ol>
Define the area as active:
<ol>
<li>At present the '''2d_code_M01_001_R''' is not active. Using the 'Identify Features' tool click on the '''2d_code_M01_001_R''' region in QGIS. The attribute 'Code' has a value of 'NULL'.
<li>Right click on the 'NULL' value and change the value to '1'. Click 'OK'. <br>
<li>The feature ID 'fid' attribute is unique to GeoPackages. Leave this as 'Autogenerate' and QGIS will automatically assign a value.
<li>Toggle the editing off to save the edits.<br>

Use the TUFLOW plugin for styling the code polygon layer to make it easier to work with:
<ol>
<li>Change the symbology of the '''2d_code_M01_001_R''' layer to make it easier to work with.
<li>Left click the '''2d_code_M01_001_R''' in the Layers panel to select it.
<li>Select ‘Apply TUFLOW Styles to Current Layer’.
<li>This updates the styling of the layer to display points on the region vertices and set the opacity to 25%.<br>
